Check out The LED flashlight is advanced high-quality aluminum alloy, durable enough to use for a long time. It is waterproof, but do not put it into the water for a long time. With XML-L T6 light bulb, its highest brightness is up to 3800LM. Using free telescopic lens, you can adjust the focal distance as long as you want. Crenellated attack head is designed for self-defense.

My words -
This torch is for specialist professional use only. It can draw a great deal of attention and be seriously offensive when in use. Both high and low beam produce a very vivid, piercing and intense light that has a blue tinge, akin to the latest car headlights on BMW's and Mercedes, etc. This torch was used by the Army on machine gun mounts in Sierra Leone and ideal for long distance riot control and also used by the English Sea King search and rescue helicopter units.

Temperature of the glass lens after I measured it with a digital probe reached 158°F (70°C) after 20 minutes continuous use. The Infra -red filter will not last long exposures due to heat involved and caution is advised the lens not be obstructed by any flammable material. The infra-red filter used in this video does not come with the torch and is only demonstrating the effect by balancing a sheet of IR plastic over the lens. Vigilance is needed in order not to warp or melt the filter using this make-shift method of producing an invisible infra-red beam.

Filmed on a Canon XA10. The Canon XA10 camera comes equipped with infra-red mode with the viewable option of green or white output. I found the IR white filter rendered better results than green.

Demonstration of the amazing thermal properties of TCPG.

Layers of endless perfect aligned Graphite crystals showing an amazing thermal conductivity of 1900 W/mK in the X-Y plane.
Not yet close to the perfect Graphene which theoretical value is 4400 W/mK
More than double the thermal conductivity of pure Diamond.

Still TCPG thermal conductivity is 5x better compared to Copper and Silver.
Building TCPG in your Aluminium design (package) will boost the thermal properties of your Aluminium design.

Beside thermal conductive it is also electrical superconductive at room temperature. With the right setup of magnets it is hovering endlessly above the magnets at 20 C

Even better is the diffusivity, the heat transfer speed.
Because of the low specific weight compared to Copper (4x lower), the heat transfer speed is 20x higher compared to Copper.

Touching the icecube, you will feel the cold ice temperature reaching your fingers in 1 second. The energy flows from your finger to the edge where it touches the ice and the ice melts away.
With Copper it will take around 20 seconds over the same distance.

It is used at CERN for the Atlas project to cool the sensors from a long distance without using fluid cooling. atlas_sct/
TCPG is still pretty expensive because the energy that is used to reach the extreme temperature of over 3200 Celsius to process the material.
